answers are confusing me. you are at 3mg basically because it satisfies you. Question is if I'm at 12mg now on a iCare and moving to an RDA squonker, will this affect now much nic Im getting and therefore should step down to avoid a headache.
that depends on what you build your RDA to. what RDA are you getting?
if you desire, it's possible to set it up almost identical to your current icare setup, and still use 12mg.
it's also possible to build it to .2 or .3 ohms and still use the juice you're using.
it's also possible that that will give you too much nic. everyone is different. every juice is different.
yes, most people reduce their nic when switching to that setup. some don't. if I were you, I'd get the same juice that you're currently using, and then get an extra bottle of 0 nic juice. If what you have it too nic heavy, you can dilute it until you find your sweet spot.
hope that clarified some stuff. good luck!
